The squamous cell carcinoma of the external auditory canal is extremely rare. The facial paralysis is usual, but pain seems to be the most common symptom. The mean age at diagnosis is 50 to 60 years, with chronic external otitis preceding. The CT-scan is the most important investigation before treatment: surgery and external radiotherapy. Surgical procedure must be large, with or without facial nerve dissection, following by irradiation of the temporal bone and cervical nodes. The generally poor prognosis is explained by the frequency of advanced disease at the time of diagnosis. This paper reports our 4 experiences, with a bilateral carcinoma case.
外耳道鳞状细胞癌极为罕见。面瘫较为常见，但疼痛似乎是最常见的症状。诊断时的平均年龄为50至60岁，之前常有慢性外耳炎。CT扫描是治疗前最重要的检查手段：手术和体外放疗。手术必须范围广泛，可进行或不进行面神经解剖，随后对颞骨和颈部淋巴结进行放疗。诊断时晚期疾病的发生率导致总体预后通常较差。本文报告了我们的4例病例，其中有1例双侧癌病例。
